ILS tuning question.

[RedSpinnaker 35]

Hello. I have a quick question regarding tuning an ILS. I think I'm doing it right, but obviously I'm missing something.Was inbound on the KORD JVL4 arrival on VATSIM with Center staffed. After getting turned for vectors for ILS 27R (IIAC), I went into "dumb" autopilot mode (HDG Select, ALT Hold and MCP Speed), disconnecting VNAV and LNAV. I tuned the ILS freq (110.5) into both COM1 and COM2, shifted them from standby to active, and dialed in the approach course of 270.This all happened while I was still to the northwest of KORD, so I expected the nav radios to pick up the 9L ILS (IJAV) since it's on the same freq (which they did). Well, the NAV radios never succeeded in changing over and picking up/displaying the 27R ILS, even while being vectored onto final with my ILS approach clearance (well to the east of the field). I tried several times to change freqs and re-tune, but each time I shifted the freq back to the active, it displayed the 9L approach (while I was on the 27R).I finally had visual on the field at 11 miles, so asked for the visual, killed the A/P and hand flew her in (it takes an event like this to remind you how much of a joy it is to fly this bird).Anyone have any recommendations? Ideas?Thanks,-Dan

Just a shot in the dark here, but did you still have the original runway entered in the FMC? Also, did you switch the ND from MAP to ILS/APP. Can
